100%.
That said that Motion Pro fuel line is ungodly nice. Even the cheap stuff.

I cannot answer for all, but I use fractional size because I can get outstanding quality fuel line (Goodyear SAE 30R7) in fractional but not in metric sizes. Unlike some other fuel line I used in the past, including the original Kawasaki fuel line, ethanol fuel does not affect the Goodyear product at all. I use 5/16” fuel line and it fits well with zero leaks. The difference in size doesn’t seem to affect the fit at all since the fuel line is pliable. The size I use is slightly larger than stock, so it doesn't reduce fuel flow. I wouldn’t mind using the metric sized line if it was available from Goodyear, but they do not list it on their website (see link below) in metric sizes. If they ever offer it I might switch back to metric. Ed

Neither the Kawasaki dealer nor a cycle shop near me had metric. z1enterprises doesn't have metric either.by Nessism: Why do people use fractional sized hose/tubing when the bike is designed for metric?

I thought the original fuel line was 8mm, nominally, since that's the closest to the actual measurement of the pipe. That means 5/16" (7.9375mm) would be slightly tighter. But 5/16" fuel line gets loose, and on hot days, might start leaking, without a clamp. So maybe the original fuel line was nominally 7mm?

The OEM fuel hose is 7mm ID (or something very near). I've mentioned this before but the best fuel line I've found is sold by Suzuki (Part# 09352-70103-00B). Order this stuff for about $9 and you get something like 5 feet of the stuff in the package. It's stretchy and thin walled. No need for any clamps to keep it from leaking yet you can push it off easily when removing the fuel tank.
For the overflow lines on the carb floatbowl nipples I bought some 3.5mm fuel tubing from Honda. Great stuff, but a little more pricy. It's worth it though in my view because again, it's thin and you don't need any clamps. Automotive vacuum hose tends to be fatter than necessary.
BTW, I bought some of this stuff but it's crap. Nothing like that nifty Suzuki fuel line. It's stiff and doesn't stretch very well. Stay clear of this stuff...

This comes up as 4.5x8.5x600. What do the numbers mean? if it's ID x OD x length, then is that the right number?Suzuki (Part# 09355-45855-600)
I found it mentioned as a vacuum line.
Quote from this forum: www.thegsresources.com/_forum/archive/index.php/t-216193.html
The vacuum hose part number is 09355-45855-600. Looking at the second half of the number (after the "-"), it tells you that it is 4.5mm inside diameter, 8.5mm outside diameter, probably from vendor #5, and is 600mm long (quite a bit more than you need).
The fuel hose part number is 09352-70103-00B, which tells you that it is 7mm inside, 10mm outside (from vendor #3?). The length is not given in the part number, but I have received about 2 meters (6 feet) of it when I order it.
Could it be that we want part number 09352-70103-00B? That part comes up as a drain hose for water. But maybe it is used for fuel too, as others seem to use it for fuel. EDIT: other suppliers list it as "fuel".
And yes, stay away from any glossy hose. I've tried many, and all failed. Maybe they can work a short while without corn-fuel, but that's almost impossible to get around here.
